A convenience sampling method was employed to recruit 445 food service employees from 67 Chinese restaurants across all 16 administrative districts of Beijing City from August to December in 2022. A questionnaire survey was conducted to assess their knowledge, attitudes, and behaviors regarding salt reduction and hypertension. The results revealed that awareness was highest for the statement "Hypertensive patients should reduce salt intake" (88.3%), while awareness of "China′s diagnostic criteria for hypertension" was the lowest (23.8%). Positive attitude endorsement rates were 96.0% for willingness to reduce salt, 95.3% for perceived self-efficacy in salt reduction, and 93.0% for agreement with a low-salt diet. Regarding behaviors, the rates of actively reducing salt when ordering takeout or dining out, using low-sodium salt, and using salt-reducing spoons were 73.7%, 45.4%, and 55.5%, respectively. The overall compliance rate for salt-reduction related behaviors was 73.9%. Multivariable logistic regression analysis demonstrated that: compared to the 18-29 age group, employees aged 30-39 ( OR=2.19, 95% CI: 1.16-4.14), 40-49 ( OR=3.36, 95% CI: 1.52-7.42), and 50-59 ( OR=3.25, 95% CI: 1.25-8.50) were significantly more likely to achieve compliance with salt-reduction behaviors; chefs were significantly more likely to achieve behavioral compliance compared to managerial staff ( OR=2.08, 95% CI: 1.08-3.98); employees in catering with adequate knowledge about salt reduction and hypertension were significantly more likely to exhibit behavioral compliance compared to those with inadequate knowledge ( OR=3.32, 95% CI: 1.83-5.92); employees in catering with positive attitudes towards salt reduction were significantly more likely to achieve behavioral compliance compared to those with negative attitudes ( OR=5.81, 95% CI: 2.05-16.43). In conclusion, food service employees in Beijing exhibit insufficient knowledge about salt intake and hypertension. While they demonstrate strong willingness to reduce salt, this does not consistently translate into action. Compliance with salt-reduction behaviors is influenced by age, education level, and job position. There is an urgent need to strengthen the dissemination of knowledge regarding high salt intake and hypertension and to implement personalized interventions targeting salt-reduction behaviors and skills.

The angiogenic response is essential for the repair of ischemic brain tissue. Integrin α6 (Itga6) expression has been shown to increase under hypoxic conditions and is expressed exclusively in vascular structures; however, its role in post-ischemic angiogenesis remains poorly understood. In this study, we demonstrate that mice with endothelial cell-specific knockout of Itga6 exhibit reduced neovascularization, reduced pericyte coverage on microvessels, and accelerated breakdown of microvascular integrity in the peri-infarct area. In vitro, endothelial cells with ITGA6 knockdown display reduced proliferation, migration, and tube-formation. Mechanistically, we demonstrated that ITGA6 regulates post-stroke angiogenesis through the PI3K/Akt-eNOS-VEGFA axis. Importantly, the specific overexpression of Itga6 in endothelial cells significantly enhanced neovascularization and enhanced the integrity of microvessels, leading to improved functional recovery. Our results suggest that endothelial cell Itga6 plays a crucial role in key steps of post-stroke angiogenesis, and may represent a promising therapeutic target for promoting recovery after stroke.

Anti-tumor traditional Chinese medicine has a long history of clinic application, in which the star molecules have always been the hotspot of modern drug research, but they are limited by the solubility, stability, targeting, bioactivity or toxicity of the monomer components of traditional Chinese medicine anti-tumor star molecules and other pharmacokinetic problems, which hinders the traditional Chinese medicine anti-tumor star molecules for further clinical translation and application. Currently, the nanosystems prepared by supramolecular technologies such as molecular self-assembly and nanomaterial encapsulation have broader application prospects in improving the anti-tumor effect of active components of traditional Chinese medicine, which has attracted extensive attention from scholars at home and abroad. In this paper, we systematically review the research progress in preparation of supramolecular nano-systems from anti-tumor star molecule of traditional Chinese medicine, and summarize the two major categories and ten small classes of carrier-free and carrier-based supramolecular nanosystems and their research cases, and the future development direction is put forward. The purpose of this paper is to provide reference for the research and clinical transformation of using supramolecular technology to improve the clinical application of anti-tumor star molecule of traditional Chinese medicine.

MicroRNAs(miRNAs)are small non-coding RNAs that are closely associated with the occur-rence and progression of tumors and other diseases.However,miRNAs require high-sensitivity and high-specificity detection due to their low abundance,high sequence homology,and rapid degradation.The RNA-cleaving deoxyribozyme(RCD)is a functional single-stranded DNA molecule that enables specific cleavage of substrates to release miRNAs that can be recycled with the assistance of metal ions,prompting cyclic signal amplification.Recently,developing new methods based on RCD catalytic amplification for miRNA high-sensitivity detection has become the focus of researchers.Based on combing with the various new technologies and materials in miRNA biosensors,this study classifies and reviews the new methods for detecting miRNAs based on deoxyribozyme catalytic amplification developed in recent years.We sepa-rate these miRNA detection strategies into three categories:RCDs combined with DNA self-assembly,i-sothermal amplification,and nanomaterials.We explore the basic principles of each approach,the latest research advancements,and application scenarios in biomedical sensors and medical detection.This re-view provides a foundation and reference for further research of highly sensitive and accurate miRNA de-tection strategies.

Objective: We aim to evaluate the morbidity and mortality of cancer attributable to human papillomavirus (HPV) infection in China in 2016. Methods: Based on the cancer incidence and mortality rates, national population data, and population attributable fraction (PAF) in China, we calculated the number of incidence and death cases attributed to HPV infection in different areas, age groups, and gender in China in 2016. The standardized incidence and mortality rates for cancer attributed to HPV infection were calculated by using Segi's population. Results: In 2016, a total of 124 772 new cancer cases (6.32 per 100 000) were attributed to HPV infection in China, including 117 118 cases in women and 7 654 cases in men. Of these cancers, cervical cancer was the most common one, followed by anal cancer, oropharyngeal cancer, penile cancer, vaginal cancer, laryngeal cancer, oral cancer, and vulvar cancer. A total of 41 282 (2.03 per 100 000) deaths were attributed to HPV infection, of which 37 417 occurred in women and 3 865 in men. Most deaths were caused by cervical cancer, followed by anal cancer, oropharyngeal cancer, penile cancer, laryngeal cancer, vaginal cancer, oral cancer, and vulvar cancer. The incidence and mortality rates of cervical cancer increased rapidly with age, peaked in age group 50-54 years, then decreased obviously. The morbidity and mortality rates of non-cervical cancer increased with age. The cancer case and death numbers in rural areas (57 089 cases and 19 485 deaths) were lower than those in urban areas (67 683 cases and 21 797 deaths). However, the age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of cervical cancer were higher in rural areas than in urban areas. There were no significant differences in ASIR and ASMR of non-cervical cancers between urban areas and rural areas. Conclusions: The incidence of cancers attributed to HPV infection in China was lower than the global average, but the number of incidences accounted largely, furthermore there is an increasing trend of morbidity and mortality. The preventions and controls of cervical cancer and male anal cancer are essential to contain the increases in cancer cases and deaths attributed to HPV infection.

Objective To investigate effects of abdominal cavity seawater perfusion on serum electrolyte concentration and hemodynamics in rabbits. Methods Ten healthy New Zealand rabbits were used for the experiment. Incisions of the abdominal cavity were made in right upper and middle epigastria. Artificial seawater perfusion and draining were performed simultaneously to simulate seawater immersion. Changes in serum electrolyte concentration,blood pressure and heart rate were observed both before and after abdominal cavity seawater perfusion. Results Blood pressure and heart rate decreased significantly following abdominal cavity seawater perfusion,but no serious arrhythmia was noted. Concentrations of serum sodium,potassium and magnesium increased significantly,when they were compared with that before perfusion. Multiple correlation analysis indicated that changes in blood pressure and heart rate were inversely correlated with changes in serum potassium and magnesium (P ＜ 0. 01 ),whereas changes in blood pressure and heart rate were positively correlated with serum sodium ( P ＜ 0. 01 ). Conclusions Abdominal cavity seawater perfusion could induce severe disturbance of hemodynamics and electrolytes. Hyperpotassemia and hypermagnesemia might be the culprit for the decrease of blood pressure and heart rate. And this animal model could be used for the evaluation of effects of electrolytes on hemodynamics following seawater perfusion.
